Final answer:

The shortest distance from the point (5, 0, -6) to the plane x + y + z = 6 is calculated using the distance of a point to a plane formula, resulting in 7 / √3 units.

Explanation:

To find the shortest distance, d, from the point (5, 0, -6) to the plane x + y + z = 6, we use the formula for the distance of a point to a plane in 3D space. The formula is given by:

d = |Ax1 + By1 + Cz1 + D| / √(A² + B² + C²)

For the plane x + y + z = 6, A = 1, B = 1, C = 1, and D = -6. Substituting the coordinates of the point (x1=5, y1=0, z1=-6) into the formula, we get:

d = |1(5) + 1(0) + 1(-6) - 6| / √(1² + 1² + 1²)

d = |-7| / √3

d = 7 / √3

Therefore, the shortest distance from the point to the plane is 7 / √3 units.

The lifetime cost of Jenny's refrigerator is A. $1,528.47.

Lifetime cost is the total expenses relating to the purchase of a good, like a car, a home, or a refrigerator from the purchase date to the end of the asset's lifespan.

We can calculate the lifetime cost by using an online finance calculator to determine the total payment, including interests, for the asset and then adding up other expenses like repairs and electricity costs.

Base cost of refrigerator = $824

Sales tax = 7.13%

Total cost of refrigerator, including sales tax (loan amount) = $882.75 ($824 x 1.0713)

Average daily electricity consumption = $0.09

Total electricity cost = $262.98 ($0.09 x 8 years x 365 days + $0.09 x 2 leap year days)

Payment period for credit purchase = 3 1/2 years

Total repairs cost = $206.25 ($68.75 x 3)

Period of possessing the refrigerator = 8 years

APR = 10.54% compounded monthly

From an online finance calculator:

Monthly Payment = $25.22

Total Payment = $1,059.24 ($25.22 x 12 x 3.5)

Total Interest for 3 1/2 years = $176.49 ($1,059.24 - $882.75)

Lifetime cost of Jenny's refrigerator = Total loan payment + Electricity cost + Repairs cost)

= $1,528.47 ($1,059.24 + $262.98 + $206.25)

Thus, the lifetime cost of Jenny's refrigerator is A. $1,528.47.

Answer:

74.02 square meters.

Step-by-step explanation:

We are asked to find the area of sector of circle, whose central angle is [tex]\frac{2\pi}{15}[/tex].

We will use area of sector formula to solve our given problem.

[tex]\text{Area of sector}=\frac{\theta}{2\pi}\times \pi r^2[/tex], where, r represents radius of circle.

Upon substituting our given values in above formula, we will get:

[tex]\text{Area of sector}=\frac{\frac{2\pi}{15}}{2\pi}\times \pi (18.8)^2[/tex]

Using fraction rule [tex]\frac{\frac{a}{b}}{c}=\frac{a}{bc}[/tex], we will get:

[tex]\text{Area of sector}=\frac{2\pi}{15\times 2\pi}\times \pi (18.8)^2[/tex]  

[tex]\text{Area of sector}=\frac{1}{15}\times \pi \times 353.44[/tex]  

[tex]\text{Area of sector}=23.5626666\times \pi[/tex]  

[tex]\text{Area of sector}=74.0243004\approx 74.02[/tex]  

Therefore, the area of given sector of circle is 74.02 square meters.

The formula to find circumference of circle is given by

[tex] C = 2\pi r [/tex]

Where r is radius of circle and pi =3.14

We are given Circumference here as 361π

Plugging the value in the formula :

[tex] 361\pi = 2\pi r [/tex]

r=361/2 = 180.5

radius of circle is 180.5.

We know that Diameter is double of radius.

So diameter = 2*180.5 = 361

Answer : diameter of circle is 361.

To convert the angle in degrees to radians, multiply the angle by π and divide by 180. The ship would travel approximately 3081.23 miles.

To find the measure in radians, we need to convert the given angle from degrees to radians. There are 2π radians in a full circle, which is equal to 360°. Therefore, to convert 140° to radians, we can use the formula: radians = (degrees × π) / 180. Substituting the given angle, we get: radians = (140 × π) / 180 = (7π / 9) radians.

Next, to find how far the ship would travel, we need to calculate the arc length. The formula for the arc length of a circle is: arc length = radius × angle in radians. Given that the radius of Earth is 3960 miles and the angle of rotation is (7π / 9) radians, we can calculate the arc length as follows: arc length = 3960 × (7π / 9) ≈ 3081.23 miles.

Jason found that each soda costs $1.29 by calculating (23.33 - 15.59) ÷ 6.

Jason spends $23.33 on the pizza and the sodas, and the total cost of the pizza is $15.59. Let's find out the total cost of the sodas by subtracting the cost of the pizza from the total amount spent. So, $23.33 - $15.59 = $7.74.

Now, to find the cost of each soda, we need to divide the total cost of the sodas by the number of sodas purchased. In this case, there were 6 sodas, so $7.74 ÷ 6 = $1.29.

Therefore, Jason found that each soda costs $1.29 by calculating (23.33 - 15.59) ÷ 6.

Cost of each soda (x) is approximately $1.29.

Jason buys a pizza for $15.59.

The cost of the pizza is $15.59.

He also buys 6 sodas:

The total cost of the pizza and sodas is $23.33.

Each soda costs the same amount:

Let's denote the cost of each soda as x.

He spends $23.33 on the pizza and the sodas.

The total cost can be expressed as the sum of the cost of the pizza and the cost of the sodas:

15.59+6x=23.33.

Now, Jason finds the cost of each soda by calculating (23.33 − 15.59) ÷ 6.

This expression represents the cost of each soda.

Let's calculate it:

[tex]\frac{7.74}{6} \approx 1.29[/tex]

So, Jason finds that each soda costs approximately $1.29.

The upper bound of a 95% confidence interval if the sample mean is 2.96 is 3.16.and this can be determined by using the formula of standard error and margin of error.

Given :

First, evaluate the standard error by using the below formula:

[tex]\rm SE = \dfrac{\sigma}{\sqrt{n} }[/tex]

Now, put the values of n and [tex]\sigma[/tex] in the above equation in order to determine the standard error.

[tex]\rm SE = \dfrac{2.26}{\sqrt{506} }[/tex]

SE = 0.10

In order to determine the margin of error multiplies the standard error by 2.

ME = 0.1 [tex]\times[/tex] 2

ME = 0.20

Now, add the margin of error and the sample mean in order to evaluate the upper bound.

= 2.96 + 0.20b

= 3.16

The upper bound of a 95% confidence interval if the sample mean is 2.96 is 3.16.
